How Falmouth compares
Small towns rarely get published solar figures, so here are the numbers for Falmouth. It is one of 14 Cornwall towns we track, and it ranks 6th of 14 for solar yield, a town of 24,298 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,056 kWh per kWp a year, 2.89 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £941 of year one benefit, £247 of it from your own generation and £694 from export at 12p.
These are starting numbers, not a quote. The calculator below opens on Falmouth's own PVGIS figure; change the panels, the battery or the export rate and it reruns. The design call replaces every assumption with your roof and your bills.
Falmouth sits within Cornwall, its local planning authority, and the House of Commons Library classes it as a small town.
The charger is in the installed price but left out of payback: charging savings depend on your mileage and tariff, which the design call models properly.

Connecting solar to the Falmouth network
National Grid Electricity Distribution (NGED) owns and runs the local electricity network in Falmouth, as part of its South West England licence area.
For a typical home the paperwork is light: a system of up to 3.68kW per phase goes through G98, which means NGED is notified within 28 days of switch-on rather than asked beforehand.
Anything bigger is a G99 case and is applied for first. NGED's guaranteed standards give 45 working days for a low voltage generation quotation, with £80 paid for each working day late.

Adding a heat pump or an EV charger in Falmouth
A heat pump in Falmouth
Solar and a heat pump pull in opposite directions through the year: Falmouth's roofs make 1,100 kWh from November to February on a 12-panel system, and 3,190 kWh from May to August. The heating season leans on the grid, so off-peak rates do the heavy lifting.
The Boiler Upgrade Scheme, open in England and Wales, takes £7,500 off an air source or ground source heat pump, or £2,500 off an air-to-air unit. Homes on oil or LPG with no mains gas get £1,500 more until March 2027 (gov.uk, checked 28 September 2026).
Charging an EV in Falmouth
From April to September, 68% of a Falmouth roof's yearly output arrives, peaking at about 820 kWh in May on 12 panels. A car parked at home in daylight can soak up what the house, at around 70 kWh of daytime use that month, cannot.
If you rent, or own a flat, and have private off-street parking, the government chargepoint grant covers 75% of the cost, capped at £500 a socket, until 31 March 2027 (gov.uk, checked 28 September 2026). The calculator above prices a 7.4kW smart charger from £1,100 installed.

Falmouth solar questions
What could a roof in Falmouth generate?
PVGIS puts a roof in Falmouth at 1,056 kWh per kWp a year, 2.89 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 6,720 kWh a year, most of it between April and September.
What would 12 solar panels cost in Falmouth?
£6,360 for 12 panels (6.36 kWp), the same as in every other place we cover, because solar is priced at £1,000 per kWp installed rather than by area. A battery adds its own installed price on top. Where Falmouth differs is output: about 6,720 kWh a year from that system.
Do I need permission from the DNO for solar in Falmouth?
Usually not in advance. NGED, the network operator for Falmouth, only needs a G98 notification within 28 days of commissioning for systems up to 3.68kW per phase. Bigger inverter or battery outputs need G99 approval first. NGED's guaranteed standards give 45 working days for a low voltage generation quotation, with £80 paid for each working day late. "See our DNO explainer.
How much would export pay on a system in Falmouth?
It is exported. With typical use and no battery, about 5,779 kWh of the 6,720 kWh a 12-panel system makes in Falmouth goes to the grid, around £694 a year at 12p. A battery keeps more of it for the evening; the export rates table shows what suppliers pay.
Do solar panels work in winter in Falmouth?
Yes, at a lower level. PVGIS gives Falmouth 33.7 kWh per kWp in December and 38.9 in January, so a 12-panel system makes about 210 kWh and 250 kWh in those months, against 820 kWh in May. Winter output mostly covers daytime use rather than exporting.
How Falmouth compares with its neighbours
Same satellite dataset, same assumptions, so the differences are real geography rather than modelling noise.
| Town | kWh per kWp a year | vs Falmouth |
|---|---|---|
| Falmouth | 1,056 | this town |
| Penryn | 1,062 | +6 kWh |
| Truro | 1,052 | −4 kWh |
| Redruth | 1,038 | −18 kWh |
| Helston | 1,110 | +54 kWh |
| Camborne | 1,026 | −30 kWh |
| Hayle | 1,102 | +46 kWh |
Each row is a PVGIS v5.2 run at that town's centre with the same settings. Treat gaps of a few kWh as noise and gaps over about 30 kWh per kWp as real differences in sunshine.
